BYou can do a search on AOD tv cable adjustment. Also jack up rear of car, support with stands, mark the driveshaft with something, with car in neutral rotate rear tire 1 full rotation, watch to see how many times the driveshaft does a full rotation. If it’s a little less than 4 times, then yes you have 3.73s. If the tv cable is not out of adjustment, you can pull the valve body out of the trans and using parts that come with most shift kits change the shift rpm. What rpm is it shifting at? I would shoot for 5800-6200 with a stock block, but it really depends on the cam where the car is making peak power...
